i make Loudspeaker boxes but nothing like that, the amount of cauclations to come up with the sound cuves and what not on that box would be a bit of a task to do. You can do it but you would have to have the right speaker you want then draw the box for that speaker and take you time diong so by testing the sound waves and what Freq you want that speaker to play at or what range you want to Make that speaker realy belt at. Can be done but you have to have alot of cauclations behind it to make it sound nice.

Just my 2 cents
